"I think it's fine," Sherman said of the rules. "It's worked so far. It's been fine with everybody. Everybody's done well and abided by the rules for the most part. I haven't seen any players adamantly come out and be like, 'I'm tired of this rule,' or 'I'm tired of this.'"

The issue of marijuana use has wafted through the air all week, and not just because the two teams in the Super Bowl are from the only two states that have legalized the drug for recreational use. Commissioner Roger Goodell said last week that the league will continue to look into possible medicinal uses for marijuana after HBO's "Real Sports" televised a segment on the issue.

The Seahawks are also playing in the Super Bowl without cornerback Brandon Browner, who was suspended indefinitely by the league for failing to comply with the substance abuse policy. Cornerback Walter Thurmond also was suspended for four games earlier this year for violating the same policy.

Not even that swayed Sherman into thinking the rules need to be changed.
